Is it normal for Pajero to have a big valve?

1. Excessive clearance between hydraulic valve tappet and cam or valve seat: Pajero's powerful valve is loud. This is because the hydraulic tappet is too worn, and the oil in the tappet quickly releases pressure, resulting in abnormal sound, so it is necessary to replace the hydraulic tappet.

2. Too high or too low oil level in the crankcase: Too high or too low oil level will lead to oil leakage from the crankcase and abnormal noise, so it is necessary to check the engine oil level.

3. Wear of the valve guide: Wear of the valve guide causes the valve to close loosely, resulting in abnormal sound, so it is necessary to replace the valve guide.

4. Excessive viscosity of engine oil: Excessive viscosity of engine oil leads to poor fluidity of engine oil, which can not fully lubricate the valve, resulting in abnormal sound, so it is necessary to replace engine oil with appropriate viscosity.

5. Foreign matter entering the valve guide: Foreign matter entering the valve guide will cause the valve to close loosely and produce abnormal sound, so it is necessary to clean the foreign matter in the guide.
